Subject [jira] [Commented] (HADOOP-7702) Show the default configuration value in /conf servlet as well
Date Mon, 03 Oct 2011 11:11:34 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7702?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13119243#comment-13119243

Steve Loughran commented on HADOOP-7702:

I don't think this should be in conf, but it may need to be accessible somehow. Why? Because
if I bring up a NN listening on I'd like to know that fact, though I'd also like to
know the live hostname ended up, and the live URL being hdfs://cluster1/

I've served up configs with these values and the prefix live. which aided management; I could
imagine serving up a conf file under a different path that served up the live values with
the names people expect -this could then be downloaded and used directly by a client program
(which is what I effectively did)
